ln the present instance 'is illustra-ted one en'ihodin'ient ot the invention which embodies the unitary feature of the apparatus, which enables it to be attached to and detached from the tail board of any coal or other similar wagon.

Referring to the drawings c represents a coal Wagon of any usual or desired construction and b the tail board thereof..

The tail board may be of any suitable or desired construction and carries a basket supporting and hoist-ing mechanism, and in the present instance a preferred construction is shown, which consists of' a tramework, a windlass supported thereby, means for supporting the` basket, and iexible means for connecting the basket supporting means `with the windlass, whereby the basket may be hoisted from its lowered or filling position into an elevated position by winding said flexible means on the Windlass.

The framework may and preferably will he constructed to cooperate with the usual chute attached to the tail board, and as said chutes vary in length on diierent wagons, 30 the 'framework is made so that it can be adjusted with relation to said chutes to enable the basket in its lowered `position to beproperly positioned with respect to said chutes.

To this end the framework is provided with a member, which is attached tothe tail board and may be designated the lstationary member, and is further provided with a .member which is movable with respect to the stationary member so that its lower end,

. which `supports the basket when empty, may

be moved toward and from the stationary member to properly position the empty basket withrelation to the chute on the tail hoard.

The framework herein shown consists of sub-parallel side frames c, d, (see Figs. 1, 3, and 5) and each side frame comprises a back member 10, a 'front member 12 and atop too member 13. The back member 10 is shown as an angle iron and the top and front members 13, 12 as pieces of iiat iron or steel. The top vmember 13 is secured at its rear end by l rivets 14 to the back member 10, and is bent 105 at its front end to form an arm 15 to which is riveted a downwardly and rearwardly inclined brace or arm 16, having` its lower end bearing` against and spot welded or otherwise secured to the back member 10, and hav- 11o moa curved upper end 17 'which cooperates with the bend in the top member 13 to 'torni a hearing for a shaft 18, upon which the front member' is mounted to turn or pivot. ln the present instance, the front member 12 is pivotally mount-ed on f the shaft 1S by an angle plate 19, (see Figs. 1, 2 and 3), which plate is secured to the front member 12'by rivets 20. The front member 12 is curved or bent at its lower end, and the said front members 12 of the side frame c, (Z, are c0nnecte'dat their lower ends byy a cross bar 21, which is 'riveted thereto. y

The cross bar 21 ties thefront members 12 together so that they can be swung on the shaft 1S as one piece, and provision is made for securing the lower ends ofthe front me1nbers in operative relation to'the usual. stationary chute 23 attachedto thetail board.y

The clips 24C are detachably secured to the back members 10 by chains 27, one endvof the chains being attached to the said clips and the other end passed through eyes 28 in the back members 10 as represented in Figs. 3 and The back members 10 are tied together by one or more cross vbars 30 and the top members '13 are connected together by a cross bar 31.

rlhe shaft 18 constitutes one form of windlass, and is connected by chains 33 or like flexible'means with a supporting device er member fora basket 3ft, and in the present instance the chains are provided with eyes 35, which engage hooks 36 on arms 37 which engage and slide upon the inner surfaces of the front members 12 of the framework, and have their ends, which project beyond the front members 12, connected by a cross bar or member 38, which is preferably curved to engage the rear side er surface of the basket 34 to steady the same when elevated and lowered. The basket 3l is provided with suitable hooks 39 which detachably engage the arms 37. The chains may be wound upon the shaft 18 or, as is preferred and herein shown, may be wound on a sleeve or drum 40, which is loose on the shaft 1S and is capable of being coupled with the shaft to rotate therewith or of being uncoupled therefrom to rotate independently thereof. y

The sleeve 40 maybe 'coupled to the shaft 18 by a pin 41 on the shaft 18 entering a slot 42 in one end of the sleeve, as shown inFig. 1.

By reference to Fig. 1, it will be seen that by moving the sleeve 40 on the shaft in the direction of the arrow 13, sufficiently 4to disengage it from the pin d1, the sleeve is rendered loose on the shaft so as to turn thereon while the latter is held stationary by a holding pawl da. This arrangement is ef advan` tage it provides for a quickreturn by gravity of the empty basket to its filling posit-ion, as will be described. The holding pawl engages a ratchet wheel Ll5 on the shaft 18. The pawl l-,il is pivoted to a lug aG on the cross bar 31.

f Thebaskethoisting or lifting apparatus above described may be permanently attached to the wagon and preferably to the tai board b, but it is preferred to detachably secure it to the tail board, and in the present instance a simple and' quickly oper- .d method of attaching it to the tail board is employed. To this end, the tail board 7) has attached to it devices for engaging the lower ends ofthe back members 10, which devicesare shown as hooks 7, which have their free ends separated from the ltail board a suliicient distance to permit the back members 10 yto be slipped behind the heoks '-17,

bymoving the framework downward from `to extend over the upper surface of the tail board, and having arms 50 which are designed to engage the inner surface of said tail board.

rl"he arms 49 are made longenough to extend through the back members 1() and are threaded at their ends to receive hand nuts 51. The arms 50 of the hooleshaped devices may be connected by a cross bar 52 which engages the inner surface of the tail board. The hook-shaped devices and the connecting bar 52 may be made of a single piece of metal rod suitably bent at its ends. 1

The back members 10 may be reenforced at the parts through which the threaded arms l19 are extended, by blocks 53 against which the nuts 51 bear, and said back members 10 may be provided with a plurality of .holes 54 for the passage of the threaded arms L19, so as to enable the hoisting apparatus to be adjusted to tail boards of different heights.

From the above description, it will be seen that the hoisting apparatus as a unit can be quickly and easily attached to and detached from the tail board of the wagon.

The tail board 5 is provided with the usual outlet opening for the discharge of the coal ,into the chute 23, which opening is normally ,closed by a slide or valve 55 movable in guides 56 vand whichy is shown as raised and lowered by a lever 57 (see Fig. 1).

The hoisting apparatus herein shown is applicable to coal wagons of all kinds and particularly to those Whose bodies are elevated at their iront ends to facilitate the discharge of the coal into the basket, and suoli a wagonbody is represented.

The hoisting apparatus, when applied to such a wagon, enables the load to be delivered by one man, to wit: the driver oi' the wagon. l

ln operation, the basket Pri is automatically i'illed when in its lowered position shown in Figs. 1 and 3 by manipulating the lever 57 to open they discharge openingin the tail board.

lihon the basket is iilled or loaded, the operator turns a handle 60 on the sha-tt 18 to wind the chains l33 upon the windlass et() and draw the loaded basket up into a. suitable position to be transferred to the back of the operator, which is easily done by the operator backing up to the elevated basket and then alter grasping the basket walking away trom the hoisting apparatus, so as to disengage the hooks 89 trom the hoisting apparatus.

ilVhen the operator returns to the Wagon with the empty basket, he engages the hooks 39 with the arms 37 and then moves the sleeve e() in the direction oi' the arrow 113 so as to uncouple the sleeve from the shalft 18, whereupon the basket can descend b v gravity to its lowered or iillinrj position. The descent oit the basket may be regulated by the operator restrainingil rotation oi' the sleeve more or less with his hand or otherwise.

il] hen the empty basket has been lowered into its filling position, the sleeve l0 is again coupled with the shaft 18 and the apparatus is again. in condition to hoist the basket and its next load.

It will be observed that the return the empty basket to its filling' position is quickly aeromplished, and a. result the wagon may be 4unloaded in a minimum time.

,it will further be observed that the wagon van be unloaded with a single operator with a mininulm oi? labor on his part, and in practice it has been 'found that a single oo-` erator can unload the wagon with less labor and in less time than was required by two men formerly.

The hoistingapparatus is not only benefieial to the operator, but also to his employer as it shortens the time of delivering a load, and lessens the number of men employed to deliver a given quantity of eoal per day. Furthermore it is ot advantage when two men `fo with the wagon, as both can carry the coal from the wagon to the bin and the number of loads delivered per dav is increased.

rlhe apparatus is furthermore simple, relatively 'light and easily handled, and is highly eliicient in use.

lt will be observed that by turning` back the nuts 51., the hoisting apparatus is free to be removed from the tail board, which is effected by moving the apparatus upwardly until the beveled lower ends iS ot thel ba-eli members rr ter with the hooks L17, whereupon the al `paratus ears be tilted away from the tail board and removed therefrom.

it is to be observed that the windlass employed to hoist the basket is shown as earried by the tail board ot the wagon, by means or the framework., which is detachably secured thereto, and while this arrangement is preferred it is not desired to limit the invention in this respect.

@ne embodiment ot the invention is herein shown, but it is not desired to limit the invention to the particular construction shown.
